To all 1li/wm z't may concern:

Be it known that I` FREDERICK G. HUGHES, a citizen of the United States, residing at Bristol, county of Hartford, State of Connecticut, have invented a certain new and useful Antifriction-Bearing, of which the following is a full, clear, and exact description, such as will enable others skilletl in the art to which it appertains to make and use the same, reference being had to the fthcompai'iying specification. My invention relates to antifriction bearings and more particularly to bearings of the type having a separator or spacenfor the antifriction members thereof. In beau ings of this type as heretofore constructed ditliculty has been experienced in providin r a simple two-piece separator which, while strong and rigid, could at the same time be inexpensively manufactured and accurately and quickly assembled.

One object of my invention is to provide a. two-piece separator of stron and rigid, and at the same time, inexpensive construction, and which may be'easily and accurately assembled.

Another object is to" provide an antifriction bearing, having a separator for its antifrictioii members whose parts always maintain their proper alinement and spacin f nother object is to provide a separator whose 4sections are rigidly connected to resist the wedging action of the antifriction members.

' Another object is to provide an antifrie- `tion bearing having inclined raceways and having an eliicient and rigid separator peculiarly adapted to fit between the raceways of the bearing members. i

Another object is to provide a separator whose construction is strong and rigid and bodying at the'same time such as to peculiarly adapt the separator for use in a bearing having inclined raceways.

To these ends and also to improve genen ally upon devices of the character indicated, my. invention consists in the various matters hereinafter described and claimed.

In the accompanying drawinvs: Figure 1 is a side View of an assembled earingem my invention; Fig. 2 is a section on Specification of Letters Patent.

line :r`m of Fig. 1; Fig. 3 is a side view of an assembled separator and antifriction members, a portion of one of the separator sides being broken away; Fig. 4 is a plan view of thc separator illustrated in Fig. 25, portions thereof being broken away; and Fig` 5 is a sectional view of a modified separator.

The illustrated embodiment of my invention comprises a separator, designed generally as 5, shown as composed of but two l: preferably annular opposed sections (l and fr' which I and rear plates may terni front provided with respectively. Each section is ball pockets, vided. as yte,.,1frally, with a preferably circular series of connectors, spacers, braces or fingers, as 8. These fingers arc provided for `connection with the opposite plate, as 7, and

serve to space and to rigidly connect the plates.

Preferably the fingers periphery of one section, as 6, and abut against and are connected with the opposed Section, as 7, approximately along the line defined upon suci opposed section by the adjacent ends of the rotation axes of the antifriction members received in the separator and here shown as the balls B. Preferably, and as here shown, this line approximately corresponds with the center line of the section and, therefore, as here illustrated, the peripheral fingers of one section meet the other approximately along its center line. With the lingers thus disposed the fingerreceiving section is rigidly connected to the lingered section` at the points where the greatest wedging stress,` from the antifriction members, occurs upon such fiiiger-re ceiving section. This wedging stress is due to the separator, which is carried by the balls during their travel, lagging behind the balls with the effect that the balls wedge into the forward sides of the pockets -of the separator and tend to spread the sections.

's stress 'is evidently greatest adjacent the ends of the rotation axes of the antifriction members.

As here shown, sections 6 and 7 are both provided with peripheral fingers 8 and .9, respectively, abutting the opposed section substantially along its center line. In this construction each section is braced not only are arranged at the as 1Q. One plate, as (i, is prrrvsii at its periphery but also at its center line and cach is connected to the other along the f ills ot' the rotation axes of the antil'rietion members. Preferably the fingers of one section, (l. are at its outer periphery and the fingers ot' the other section, are at its inner periphery. 1n this way the elements ot' a pair ot' fingers are radially spaced and each section is, therefore. supported by a plurality of. pairs of radially spaced struts. Thus, any teetering of a section about the end of a finger is obviated and also. when the sections are placed together, they are not liable to become bent or otherwise thrown out of alinement.

Preferably, and as Shown in Figs. 1 to 4, inclusive, one section, as G, is of lesser diameter than the other section` as 7, in order that the fingers S and i) shall be Straight and shall he perpendicular to the body por tions of the sections. iVith the fingers straight, rather than bent or curved. they are not liable either to buckle and permit the body portions to approach and thus bind the balls or to straighten out and thus permit the body portions to recede from each other. Tith the fingers perpendicular they are not liable to bend at the point of connection with a body portion when either body portion is subjected to a. laterally applied load tending to force it toward the opposed body portion. Moreover, not only docs a particularly simple, strong and ellilient structure result from the construction immediately above described, but also, a separator having the forni that the above construction produces-one section of greater diameter than the other-is of a form peculiarly well adapting it for use in a bearing the race members of which have inclined vaceways. Thus, referring more particularly to F ig. 2, the above described separator is shown as assembled about, holding and separating the balls'B of a bearing comprising the outer race member l and the inner race member .2 having the inclined raceways ln and 2, respectively. The inclinations of the raceways are provided by the substaw tially radially inwardly projecting shoulder il and the substantially radially outwardly projecting shoulder 4. iVitb the races providcd in this usual and illustrated manner, it will be seen that a separator, to be prop crly accommodated between the race members, should have one side of greater diameter than the other. Evidently the illustratcd and above described separator fulfils this condition and is thus well adapted for use in such a bearing. Moreover, in a bcariug, such as that illustrated. having its load liuc f/-ll/ at approximately 35 to the radial line. when thc separator sections are supported (by the fingers) along the respective ccntcr lines ot' the sections. they are at the same time supported approximately along the lines defined upon the sections by the respective adjacent ends of the rotation axes ot' the antifriction members.

The lingers of cne section may be con-r nectcd to the opposed section in any suitable manner. As here shown the fingers of one section are shouldered, as at C, to abut and support the other section and the eX- tension of a linger above its shoulders is passed through an aperture in the mating section and may be fastened as by upsetting, as indicated at D. Since in manufacture, the sections are preferably stamped out, and the dies so made that all of the fingers ofv bcth sections are ot the same length below their abutments (shoulders C) it will be seen that when the sections are assembled their body portions will be equispaced throughout their lengths.

The separator illustrated in Fig. 5 is designed more particularly for use in bearings whose raceways are not inclined. It is shown as comprising two sections of equal diameter having their fingers bent each at au acute angle` as indicated at F, whereby to bring the fingers of one section approximately to the center line of the opposite section and thus approximately to the line def-ined upon such section by the adjacent ends of the rotation axes of the antifriction members. lBut even in this type ofFig. 5 the fingers are substantially straight. That is, they are straight as compared with fingers used in certain separators and which fingers are bent semi-circularly to provide a semi-cylindrical portion adapted to serve as one half of a receptacle-for a spacing ball. '.lhese substantially straight fingers are not open to the liability to buckle or straighten out present in fingers of the semicylindrical type, and therefore are well adapted to holding the body portions of the separator sections rigid with respect to each other.

Each section is shown as provided with the before referred to ball pockets 10 preferably formed to approximately conform to the surface curves of the antifriction members. These pockets not only retain the antifriction members in position but their surfaces, next the members, may serve as snpports for films of lubricant. Itis to be nrted that, since the separator is in two originally separate sections these pockets may be formed in the sections prior to the assembling of the sections about the balls, whereas. were the separator in a single piece, the pockets must needs be formed in the two sides. after the introduction of the balls. [n this. latter case there would be great danger of iniuring thc balls as well as great difficulty in properly shaping the pockets.

Preferably the balls B are received Sufficiently` loose in the separator to provide suftic-lent play to permit the series of balls being snapped over the inner rareway the rea the inner rare ineniier ii" rator then norinaiif: retaz t. '1 L the inner rare nieniher eren though the saine he reniorial from the outer rare inendier.

It wili he seen that I have pimided a hearing haring a separator of siinpie. riti cient, rigid and inexpensive ronstrnetion. u'hieh unir he eafsil)1 assen'ihied. the sections of whirh are seeurely supported against crosswise heading, rit-'idly inaintained in alinenient` and fad eonnerted againt xspreading and which, withal. may hare a character particaiarb1 irei adapting it for use between rare nleinherV ha if ineiined or generally ohiiane rareways.
